Abstract
A microform article useful for producing composite images has an image-forming layer separate from a photosensitive layer and allows for the subsequent addition, when needed, just prior to imaging, of a second photosensitive, resist layer for an add-on image. The unique construction and method therefor provide a positive or negative first image, with the possibility of either positive or negative additional images, the images not necessarily being in the same phase.
